Join RBO at the Island Spring 5k & 10k, a scenic race along the shores of Alameda hosted by Outfront Endurance. The course winds through one of Alameda's most charming waterfront neighborhoods, with views of the estuary and SF Bay throughout.

Whether you're toeing the line for your first race or chasing a personal best, there's a distance for everyone — including a ½-mile fun run for our youngest runners. Races start at the Bay Farm Ferry Terminal and finish nearby.
